What distinguishes the Sugino GiGas line from their 75 line? $500+ for a crankset or +$300+ for a chainring seems to insinuate that it's made from a superior grade material and machined to exacting standards. Hell the cogs are around $100. I'd like more information about what warrants such a premium as well as pictures.

I doubt anyone here uses this stuff, unless they are Keirin racers (Tomity-san), store owners, or trust fund babies.

I think they are made of unobtanium, whereas my cranks are made of craptanium.

Beautiful polishing, teeth are individually shaped in part by hand finishing, surface hardened. They are absolutely gorgeous and the Gigas chainring is noticeably quieter than a Dura Ace chainring when I swap it out. I got a new 14T Gigas cog on eBay for $30 and it's pretty smooth as well but -- unless you value the weight of alloy over durability -- it's actually just about beat in finish and design by the new Phil Wood cogs.

A gigas chainring was on a recent eBay purchase of mine. It is definitely quieter than the Sugino 75 series and mirror polished. A beautiful thing, but yeah - it is a lot of money for a chainring. I think with bike equipment more than just about anything else, you get what you pay for.

I use Pam.

Honestly.

Don, that coating is the surface hardening. It's an electro-chemical dip followed by a heat treatment. It helps create the very smooth bright finish, but it comes out of the dip discolored so a buffing brings up the pretty cosmetics of the finished product. I don't think it really cuts down on chain wear, but it does resist perspiration oxidation spots a lot better than Dura Ace or Campy. The hand-shaping of the individual teeth actually just takes off the first metal to be worn off by the chain anyway, so it actually does last a good bit longer than other rings at a third the price. I wish they did a steel rear cog, because the alloy one is heat treated but still won't have enough longevity to justify the price. I put the one I got cheap on a Mavic disc and it only gets ridden on those wheels.

awesome.

I ride that ____ on my beater. We are not all posers like you.

Don,

Correct, they only do an alloy one. It runs ultra smooth, but it doesn't last that long and if it's going on a Mavic disc anyway, I'm obviously not that concerned about weight. I'd rather have a piece of steel machined that well, which is pretty close to what the new Phil's are. Thanks for the clarification.

LOL

nice link 165 on the pamphlet

HA. I ride that ____ on my 12-speed bicycle co-op conversion. My chainline is like a 45 degree angle, so I figured I need every bit of durability/quietness I can get.

It only cost 4 times what I spent on wheels, it was a no brainer.

HOLLA @ YOUR BOY

HOLLAAAAAAAAA


Next up, solid DIAMOND chainrings. My rhinestone shliz is gittin' all scuffed up already.
